> As we move IT, I would like to know if we can programmatically determine the width of that adjustable space [associated with a tab] and the corresponding X and HPOS of the next character.  [Once those values are known, I can place fake cursors along that adjustable space.]

You have it.pixel_width.

As for HPOS, it always moves by 1 for each glyph, so there's no notion
of "width" for it.
